"The Sing Off" is another lame contest show, but it's cheap to produce.

Yeah ... it never quite clicked. The "silly" spy vs spy show with both having their own pasts to hide from each other. The former love interest and hemorrhoid helpers. The screw up sister. The buried "I'm not telling them why I've really recalled them" secret storyline with no apparent development. Too many better shows out there.
